Three days to go with my freccia rosso to the MV Agusta Club meeting at St. Goar and the shit hit the fan again.
A last test ride by my best friend, the engine was running fabulously, suddenly lost power and the beauty ended in smoke. Later he disassembled the head and the cylinder to find this.
It is to cry ! Now was everything finally done, the 350 run perfectly in Spa and now it is stranded again. Jesus Christ !
Okay I will be still going to St. Goar and ride a Brutale 1090 instead, there is no crying about spoiled milk.

Not good Haupti but you're right no use crying over spoiled milk. What worth a look in to is what caused it. Poor piston material? Detonation? Could be by the look of it. Poor fuel or something to do with ignition timing?

Sorry to hear of that (substantial) failure Ralf.

I have rebuilt engines on BOTH my 350s, so I feel your pain. I am getting more engine noise that I would like at the moment & am thinking the valve clearances need to be checked but I have only done them 12 -1300 klms since last adjustment.

I think you need to have a special disposition to owm & love one the old classics. I look forward to her revival :)

Oh so true, but aren't they beautiful...

I've been thinking about how to go about re-creating the classics, a bit like the one pictured in JSM's avatar, but with a modern basis, a bit like the Ducati Sport Classic 1000 S, but maybe starting with a Brutale as the donor.

Yes they are indeed beautiful & a world apart when you ride them - you are transformed back to that period, even though modern cars & bikes surround you once you hit a quite stretch of road you can be immersed in the era completely.

I am working on a version of JSM's bike - same donor (350 Ipotesi) but with a 400 big bore kit & Magni parts - hoping to have it finished some time in November & then present to the forum :) further down the track, I'd like to go to spoked wheels & drum brakes but we'll see..first things first.

The nice thing about bikes like the 1000s is that you get yesteryear looks with current reliability - my wife's Moto Guzzi V7 Racer is the epitome of that but, you know, they are just missing a certain something, you can't build "old" into new..................

Thank You guys for the nice words. It is just such a shame after everything came finally together and the bike was completely new build up. And it seams that my 350 doesn't like the MV Agusta Germany Club Meeting. The trail of failures is just frustrating.
2007 first attempt in Berlin. My ill Baby had to many flaws in the electric, like alternator producing no reliable power, the regulator overcharged or didn't charged the battery, one day the other day the other way. The carburetors were leaking externally and internally flooding the engine if not running at first kick. So i missed the tour around Berlin.
2008 Engine completely rebuild, oil in and a test ride. Everything worked fine. Next day a hugh puddle of oil under the bike. Later we found out that a little piece of the crank case central split gasket was folded over during assembling. To late to fix it for Distelhausen and I rode there a Brutale 910R.
2009 Engine again rebuild, new carburetors and it looked good. My wife there in the Sauerland with me that was great already. Okay it rained on Saturday and considering the ill electric I skipped the Tour. Sunday morning ready for the track and at the second kick the kick starter broke. Okay with some pushing i was riding both stints.
2010 The drum brakes were at a special work shop to get overhauled. The didn't got ready and my 350 was standing in the workshop lacking on wheels. I rode in Neuburg a. d. Donau a new F4 1000 and a F4 1078.
2011 Chassis completely overhauled, bushings of the rear swing arm replaced with needle bearings, new Ceriani shocks, everything resprayed (because of the acid damage from the previous years electric problems). New cable harness, new ignition coils, new alternator everything electrically complete up to date. New Ceriani replica drum brakes for the front, they are absolutely fantastic ! Everything seamed to be ready for the show. And now is the piston shot and I will ride in a few days a Brutale 1090.
Okay we will install new Mahle pistons, take the engine again completely apart and restore it again. I'm pretty confident that the failure has to do with material aging. Early ignition is clearly hearable by strong knocking and this wasn't happen at all, the engine run just fine. I fill my bike always with lead substitute additive. The valves and seats are just fine. Its just to lose your mind and faith over it. But so there is something to do for the next half year. And Freccia Rosso will be back on road and track next Year. Hopefully better than ever.

My 350 is NEVER perfect. Always something. I ended up on the side of the road with a dead battery the other night because it just wasnt charging enough. The ipotesi had issues with brakes etc...
I bought the GSXR to just ride and not worry about but I keep finding myself back on the 350 because up in the mountains and on those back country roads its just so much fun. I also finally gave both the 350s names because EVERY bike should have a name. Maybe that was my problem.

Now that's commitment with a capital C - my hat is off to you Ralf with the deepest respect.

I really think I should stay out of the other sections of this forum - the commitment & passion of the classic owners seems unmatched by the owners of the current models.

Hi chaps

It's sad to read of the woes some experience with their classics, and my sympathy too goes out to Ralf on his latest misfortune. He's a real trooper, and an MV stalwart, no doubt :yo:

But lest anyone should be put off owning a classic MV on the grounds of their unreliability, let me say that in the five years of ownership of my own bike I've had no troubles whatsoever.

I bought the bike with a slipping clutch, and a misfire caused by a loose connection beneath the tank, but having sorted these very early in my ownership it's run like clockwork ever since. Starts on the button every time, and runs like a train. And when I say I've had no troubles, I mean none. Not one. I've not even had a bulb blow!

The bike's ridden on a regular basis, and in use has seen sun rain and snow. I don't even carry tools with me on a run! I know, of course, that I'm tempting fate in writing this, but if my experience can tempt even one potential owner to buy and put his faith in a classic MV, then I'll be happy I've said it :). All any of us needs is a little good fortune!

Best of luck in fixing your bike Ralf - and better fortune with it in the future :)

Hi all.

Sorry to see that Ralph.

Interesting pistons you have there, a lot higher compression than the standard MV 350 B ones. You might need to alter your ignition timing to cope with the increase.

Interesting comment from Mr_Wryt and i had been thinking the same thing. Maybe a combination of a F4 engine in a replica 'classic' rolling chassis. Had a look on the web and it seems we are not the only people who are thinking this

http://www.jba.bc.ca/JBCycle/MVAgustaReplica.html

I find all my classics have a unique personality. Some are always reliable and happy to keep going with just the minimum of maintenence, while others can be real primadonas and require attention all the time and take every opportunity to let you down if your back is turned:)

It all just the joy of owning a classic and they can certainly teach you the art of patients!

Dorian.

It is a real joy to read that Steve :)

I don't think you are tempting fate with your post - superstitions don't rule bikes. I have read your previous posts and I note your are meticulous with your maintenance, I bet that has a much to do with your 'good fortune' but on the other side of the coin you CAN simply have bad luck as Ralf's experience. I know that he looks after his bikes very well, so it's not that.

Yes Dorian, patience is the key -you will recall my 350 rebuild last year :eek:

I curious to know how a 120+hp engine would sit an old school rolling chassis that would have been lucky to see 100hp - interesting as to how it would ride. Certainly a project that is :mouthwate to me - I think my darling wife is going to come looking for you for putting ideas in my head :laughing:

We should keep tabs on that project here me thinks ;)

Gunnar how did You name them ? Mine is called "Freccia Rosso" or "Red Bee" if she is behaving, but I have other names for her which I will not publish here.

Yeah guys as said before the bike run quite flawless in Spa and my friend is also pretty surprised. He said that there was for sure no knocking. Means that the timing was likely alright. The power loss came out of the blue. So we think that the pistons developed small cracks over the time and, yeah, any when is the time when they break. However we will look at the other piston as well and will check surely also on the timing once we get to it. I will let You know guys.
So ride safe guys I'm flying out of Oman tonight to the MV Agusta Club Deutschland Meeting. I'm so excited it will be a beautiful location, there are many friends waiting and we have a great program.

Have fun at the treffen Ralph.

Sorry i can't make it and say HI to anyone who know me.

Re your timing. 350 B has a 9.0:1 ratio, the Ipotesi has a 9.5:1 ratio. When you put Ipotesi pistons in a 350 B you actualy increase the ratio to approx 10.2:1 because of the combustion chamber size etc. It is always therefore best to add a bit more advance.

I have also had quite a few 350's with damage because of 'knocking' and it was impossible to hear it on the bike.

Hi Helmut.

No, not an expert, just had lots of experience of things going wrong and having to pull MV's apart over the years. Thanks for the kind words though:)

Keep those projects coming, before you know it you will have an MV museum!:mouthwate

All the best.

Dorian.
